"To all whom it may abnpern "Be it known that I, CHARLES L. MERRILL, of Wa-V open cylinder, 0, partly submerged g 1 it, a solid arm or branch of rod R, supporting and CHARLES L. MERRILL, or ,WAT R O N, NEW YORK.

Iettcrs Patent N o. 97 ,67 0, dated December 7, 186 9.: 3 v

IMPROVEMEN m PUMPS.

.The Schedule referred to in-theseLettez-e Patent and making part of the same.

tcrtown, in the county of Jefferson, and State of New York, have" invented a newiand. improved Pump; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, 'making a part of this specification, in which-'- My invention is represented by a vertical section.

The object of this invention is to provide, for publie; use, a simple and cheap attachment fbrpuinps, for

chamber A, and down into the well nearthesurfitce of the water, where it is attached to and supports'an' operating the pump-valveY or valve-box; 1

r 'r,sl0ts, notches, '01- holes in the walls of rod 1%, inside of the valve-chamber; a,a valve, seating upward against the annular ping upon the top of "rod above the slots or gains rr'and f e e, air-passagesinto the top of chamber A, always open. p e

The operation of this pump-attachment is simple,

convenient, and .efi'ective.

By working the pump-brake in pumping, the parts" A R O are forced up and down together. \Vhenever they are lifted, a partial vacuum is' formed in cylinder 0 and rod LB, and the pressure ,of the atmosphere willopen valve a, when the air will rush in around it,' and V 'supply the vacuum. On the downward movement of the parts A R G, the water at thelower end of cylinder 0, into, which the latter is sinking, will force thev air upward through rod R, and tend to discharge it from passages e 6, but its upward force will at once close valve (1, and cut ofi that avenue of escape. The; parts 0 R are then carried downward still further,

whenthe water of the well, rushing into cylinder 0 at the bottom, displaces a'large quantity of the air' therein, which, rising to the surface, cleanses, oxygenates, and gives life to the water, making it much more palatable and wholesome than when not. thus aerated.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is- V In connection with a'pump, P, the employment of 'an air-pump, O R A a, to force atmospheric air into the water of the well, said air-pump being worked by the ordinary pump-brake B, substantially as and for Y "the. purposes'herein described. shoulder m i'u'chamber A, and, when it opens, drop- CHAS.
